' delphia,'in the county of Philadelphia and State, of Pennsylvania,have invented new and useful Improvements in Rotary Pumps, of which thefollowing is a specification.-

. -This invention relates to rotary pumps,

with respect to discs are dis osed- 1n s dewise relation to A angleswith respect to the ra ii of the discs adjust-able stator end.

and an object of the inventionis' to provide a rotary pump which willdevelop a relatively great amount of out-going force in proportion tothe size of the pump and: the power employed for operating t. I

Another object of this invention is to rovide a rotary pump, whichisadjustab e to permit varying of the capacity. of the pump,

when desired, permitting the'samepump to be utilized with arelativelylow capacity for one capacit outlet orce of the pump. D

' A still further object of the invention is urpose or c to rovide arotary pump as specified, which p inc u-des a 'rotorcomposed of aplurality 0 discs laterally corrugated at acute angles the radii ofthe-discs,- which provide a p urality of. circumferentially ockets whichradiating the pump create a suction and provides space for receiving thefluid being pumped.

A still further object of this invention is may be utilized as a turbineor blower, by

.reversing the direction of rotation of the rotor.

Other objects of the invention will ap ear in the following detaildescription, an in the accompanying drawings wherein Figure 1 is a sideelevation of the improved pump. v

' Referring more (particularly to the drawump comprises ings, the imrove rotary e substantially a stator 1 w ich includes t tubular orcylindrical body 2, having the. 60

end lates 3 and 4 attached thereto in any fluid through the (pumpl Theendplate or head 3 is recesse in its inner. surface to provide thespaces 7 and it has a relatively ong bearing 8 formed axiall outer endof .which a' suita 9 is-mounted. The shaft 10 of the rotor le stuffingbox structure 11 is rotatably carried by the bear-v ing- S and it has arectangularportion 12,

formed thereon .at one end of which a collar 13'is mounted, while areduced threaded r- 7 tion 14 is'provided at the opposite en ofrectangular portion. The rotor plates or thereon on the discs 15 areprovided with axial rectangular I openings 16 which fit over therectangular v ortion 12 and connect the discs to the shaft f 10 forrotation therewith. The discs 15 are corrugated or cupped laterally, asclearly shown in and the corrugations are dis ,osed at acute to rovidesufiicient incline to the pockets as Figures 2 and 5 of the drawings,

in icated at 17 which are formed by the various corrugations to insurethe creatin of the necessary and proper suction throu the pump "Thediscs are disposed in si ewise relation,- one with respect to the other,as clearly shown in'Figure 2 of the drawings, thus providinga pluralityof circumferentially spaced pockets or buckets, certain of which aresubstantiall circular shaped in cross section, the outer si es of theouter discs are substantially semi-circular in cross section. Y

In the drawings, four of the discs 15 are shown, but it is to beunderstood, that any number of the discs may be utilized, withoutdeparting from the spirit of this invention and depending upon thecapacity of pump desired. To permit variation or adjustable end abutment20 is positioned "adjustment of the capacity of the pump, an '10 withinthe stator 1 'and is carried by a.

relatively large threaded. stem 21 which threads through the end 4 andis adjustable to permit variation of'the capacity space between its'nner surface, and the. inner surface of the head 3, for permittingvariationof the number of discs 15 employed to.

"circulation of fluid through the and 4 of the drawings, it will be Byparticular references to spaces adjacent to the axis of the discs, be-

tween the various pockets of the rotor to allowcireulat-ion of the fluidtherethrough.

A suitable air chamber 23 ofany approved construction may be carried bythe stator 1 and a relief valve 24 is provided to permit the relievingof the interior of the pump of air, when starting it.

It is, of course, to be understood, that the invention may beconstructed in various other manners and-the arts associated indifferentrelations, and therefore, I do not desire to be limited in any mannerexcept as set forth in the claims-hereunto appended.

What I claim is:

1. In a rotary pump, a stator, a rigid abutment at one end of thestator, an adjustable abutment Within the stator, a rotor rotatablewithin the stator between said adjustable and rigid abutments, saidabutments provided with arouate cu t-out portions gradually increasingin depth as they curve towards the outlet of the stato 2.'In a rotarypump, a stator, a rotor rotatably mounted therein, and composed of aplurality of transversely corrugated discs disposed in sidewiscengagement to provide a .lurality of circumferentially spaced poo ets,said corrugations tcrminatin at their inner ends outwardly of the axisof the disc to provide communicating spaces between the pockets, a rigidabutment at one end of the stator and adjustable abutmeutwithin thestator;

3. In a rotary pump, a stator, arigid abutment at one end of saidstator, an ad justable abutment within the stator, said abutmentsprovided with circuit cut-out portions, gradually increasing in depth asthey curve toward the outlet of the stator, a rotor within the statorand composed of aplurality of transversely corrugated discs disposed insidewise engagement one with the other to provide a plurality ofcircumferentially spaced pockets.

'4. Ina rotary pump, a stator, a rigid abutment at one end of saidstator, an adjustable abutment within the stator, said abutmentsprovided with ci cuit cut-out portions gradually increasing in depth asthey curve toward the outlet of the stator, a rotor within the statorand composed of a plurality of transversely corrugated discs disposed insidewise engagement one with the other, to provide a plurality ofcircumferentially spaced pockets, said corrugations terminating at theirinner ends outwardly of the axis of the discs to provide communicatingspaces between said pockets.

In testimony whereof I affix my signature.
